Raskind–Spiess conjecture on the Albanese kernel of varieties over p-adic fields

Let kk be a finite extension of Qp\mathbb{Q}_p and let YY be a smooth projective geometrically connected variety over kk. Write T(Y)T(Y) for the kernel of the Albanese map on the degree-zero Chow group of YY.

Raskind–Spiess conjecture. The group T(Y)T(Y) is the direct sum of its maximal divisible subgroup and a finite group.

This conjecture concerns the non-divisible part of the Albanese kernel over a pp-adic field and is motivated by work of Colliot-Thélène. Its resolution is not specified in the source.
